    A building is being knocked down with a wrecking ball, which is a big metal sphere that swings on a 10-m-long cable. You are (unwisely!) standing directly beneath the point from which the wrecking ball is hung when you notice that the ball has just been released and is swinging directly toward you. How much time do you have to move out of the way?

    A 10.0 kg ball is attached to a massless rope that is 1.30 m long. The rope is pushed to 45 degrees from the vertical and released from rest. Ignore the rotation of the ball as the rope swings, and this does not appreciably affect the dymanics. What is the potential energy of the ball with reference to its lowest position? B) How fast will the ball be moving at the bottom of the swing? and B) How long does...

    A clay ball (m=0.82 kg) is thrown at a metal target (M=1.72 kg) that is suspended from a cable. The ball is released 1.5 m above the ground at an angle of 32 degrees. There is a completely inelastic collision between the ball and the target of height of 7.1 m. At collision, the ball is moving horizontally. How far above its hanging location does the target swing?
